Abstract: (Re)construction of Financial Accounting for Profit Sharing Based on Mato System. This study aims to (re)construct Financial Accounting for Profit Sharing Based on Mato System (FAPSBMS). The method used in this study is synergy of binary opposition and participant observation. The research shows that the construction of FAPSBMS follows the rhythm of business process and produce a income statement based on single entry bookkeeping for profit-sharing purposes. This raises the distinction between FAPSBMS and modern accounting, especially in the cost of goods sold. This distinction raises the urgency for the (re)construction by combining the power of FAPSBMS and modern accounting. This (re)construction produces FAPSBMS based on double entry bookeping and Pancasila value.
